Abstract
The invention discloses a resistance spot-welding machine with floating welding heads, mainly comprising an upper welding head, a lower welding head, a welding pressure cylinder, an upper welding head installation seat, a pair of vertical guide rods installed on the upper welding head installation seat via linear bearings and a pair of vertical guide rails installed on the upper welding head installation seat, wherein the cylinder body of the cylinder is installed at the upper ends of the vertical guide rods; the lower welding head is installed at the lower ends of the vertical guide rods by means of floating up and down via a fastening bolt, a compression spring and a tension spring; and the upper welding head is installed on the upper welding head installation seat via the pair of vertical guide rails and is connected with the cylinder rod of the cylinder. While welding, the upper welding head is pushed by the cylinder rod to move downwards, and the lower welding head can be pulled by the vertical guide rods to move upwards when the downward movement of the upper welding head is limited and the cylinder body is jacked, thereby realizing the self-adaptive clamping function of the welding heads; therefore, the rigorous demands on work-piece location of common resistance spot-welding machine in high-accuracy welding are thoroughly cancelled, and the defect that components are easy to deform due to welding pressure during resistance spot-welding process is overcome.
Description
Technical field
The present invention relates to a kind of resistance spot weld, especially a kind of unsteady soldering tip formula resistance spot weld.
Background technology
Resistance spot welding is a big welding method in the electric resistance welding, also is important solder technology in the welding field.Common resistance spot weld comprises upper and lower two soldering tips, and soldering tip is fixed on the support under it, and soldering tip is installed on the elastic rod on it, and a cylinder is housed above last soldering tip.During welding, workpiece is positioned down on the soldering tip, by cylinder last soldering tip is imposed on downforce, it is closed up and clamping work pieces with following soldering tip, and then bestow electric current to soldering tip, and the electric current workpiece fuel factor that has a resistance of flowing through makes solder joint place metal alloying and realizes welding.The conventional, electric-resistance mash welder is because following soldering tip is fixed, so it can only provide a fixing working face (promptly descending the upper surface of soldering tip), during welding, the solder side of workpiece must be concordant with this working face, just can reach accurate welding.But the location of this workpiece is difficult to accomplish perfectness, and particularly concerning need be with mould fixedly the workpiece of solder joint, workpiece will be located with mould, and this is easy to form location (being the working face that the solder side of workpiece exceeds welding machine).If can not accomplish accurate location (supposing that the solder side of workpiece surpasses the working face 2mm of welding machine), when last soldering tip applies welding pressure and during clamping work pieces, will make part deformation earlier; And then be pressed on the solder joint, like this, will cause solder joint to depart from; Influence the quality (product defect that promptly causes) of postwelding workpiece because of solder joint is inaccurate; This does not allow to be permitted for accurate spot welding, so the conventional, electric-resistance mash welder is not easy to accomplish accurate spot welding.Moreover the conventional, electric-resistance mash welder requires also to be difficult to make it to be melted into flexible automatic production line or assembly line to the harshness of workpiece location, can not satisfy the needs of automated production.
Summary of the invention
The objective of the invention is provides a kind of unsteady soldering tip formula resistance spot weld to the problem in the prior art, makes soldering tip when closing up clamping, can adapt to the residing position of workpiece solder side automatically, to satisfy the requirement of accurate spot welding.
For realizing above-mentioned purpose, technical scheme of the present invention is following:
It has upright support, last soldering tip, following soldering tip; The top of described upright support connect firmly that a level stretches out on the soldering tip mount pad; It is characterized in that: the pair of vertical guide rod is installed in described going up on the soldering tip mount pad through linear bearing; A welding pressure cylinder is installed through a cylinder mounting plate in upper end at said pair of vertical guide rod; A slide block is installed in described going up on the soldering tip mount pad through the pair of vertical guide rail; The described soldering tip of going up is installed on the conducting block, and described conducting block is fixed on the described slide block through trip bolt and insulation system, and the cylinder bar of described welding pressure cylinder links through a universal joint and joint and described slide block; Soldering tip installing plate, insulation board and following soldering tip conductive plate down are housed in the bottom of said pair of vertical guide rod successively; And their fastening bolt and a pair of stage clip and upper and lower unsteady lower ends that is bound up on described pair of vertical guide rod of a pair of extension spring through being with insulation sleeve, described soldering tip down is installed in down on the soldering tip conductive plate.
The further improved technical scheme of the present invention is following:
Described pair of vertical guide rail adopts the pair of cross roller guide rail, and this pair of cross roller guide rail is installed in the perpendicular grooves of soldering tip mount pad front end face, in this perpendicular grooves, also is provided with this a pair of pretension voussoir to the intersection roller guide rail.
Can find out through technique scheme; The present invention is installed in the pair of vertical guide rod on the soldering tip mount pad through linear bearing; And the cylinder body of welding pressure cylinder is installed in the upper end of said vertical guide stem; Following soldering tip is bound up on the lower end of vertical guide stem through upper and lower the floating of fastening bolt, stage clip and extension spring, will goes up soldering tip to be installed on the soldering tip mount pad, and link with the cylinder bar through the pair of vertical guide rail.During welding, the cylinder bar promote to be gone up soldering tip and is moved down, and following soldering tip can move down limited and moves on through the vertical guide stem pulling during jack-up cylinder body at last soldering tip, thereby realizes the upper and lower unsteady of soldering tip down.Owing to the realization of the upper and lower float function of soldering tip down; So no matter which position the solder side of workpiece is positioned at; As long as this position is between two soldering tips; Soldering tip can both be implemented adaptability and clamp, completely abolished the conventional, electric-resistance mash welder in high-precision welding to the harsh requirement of workpiece location, also overcome the shortcoming that workpiece in the conventional, electric-resistance pinpoint welding procedure is subject to welding pressure generation deformation.The present invention is skillfully constructed, and operation precision is high, has guaranteed that spot welding is accurate, can satisfy the requirement of accurate spot welding fully.Moreover, because above-mentioned soldering tip self adaptation clamps the realization of function, make this welding machine can be fitted in different flexible automatic production lines or assembly line easily, form the automatic station of line body, satisfy the needs of automated production.It is that vertical guide rail has adopted the intersection roller guide rail that the present invention further improves, and it can make soldering tip more stable with the clamping action of following soldering tip, and motion process is more accurate.
